Element Vectorfield3D
JXG.GeometryElement,JXG.GeometryElement3D
↳ JXG.Curve3D
↳ Vectorfield3D
3D vector field.
Plot a vector field either given by three functions
f1(x, y, z), f2(x, y, z), and f3(x, y, z) or by a function f(x, y, z)
returning an array of size 3.
Defined in: curve3d.js.

Element Detail
Vectorfield3D
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "vectorfield3d".
- Possible parent array combinations are:
-
{Array|Function|String} F
- Either an array containing three functions f1(x, y, z), f2(x, y, z), and f3(x, y) or function f(x, y, z) returning an array of length 3.
-
{Array} xData
- Array of length 3 containing start value for x, number of steps, end value of x. The vector field will contain (number of steps) + 1 vectors in direction of x.
-
{Array} yData
- Array of length 3 containing start value for y, number of steps, end value of y. The vector field will contain (number of steps) + 1 vectors in direction of y.
-
{Array} zData
- Array of length 3 containing start value for z, number of steps, end value of z. The vector field will contain (number of steps) + 1 vectors in direction of z.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown. Parameter options:
Attribute Detail
arrowhead
Customize arrow heads of vectors. Be careful! If enabled this will slow down the performance.
Fields are:
Defined in: options3d.js.
- enabled: Boolean
- size: length of the arrow head legs (in pixel)
- angle: angle of the arrow head legs In radians.
Defined in: options3d.js.
- Default Value:
- {enabled: true, size: 5, angle: Math.PI * 0.125}
scale
Scaling factor of the vectors. This in contrast to slope fields, where this attribute sets the vector to the given length.
Defined in: options3d.js.
Defined in: options3d.js.
- See:
- Slopefield.scale
- Default Value:
- 1

{Object}
Vectorfield3D.setF(func)
Set the defining functions of 3D vector field.
- Parameters:
- {Array|Function} func
- Either an array containing three functions f1(x, y, z), f2(x, y, z), and f3(x, y, z) or function f(x, y, z) returning an array of length 3.
- Returns:
- {Object} Reference to the 3D vector field object.
- Examples:
field.setF([(x, y, z) => Math.sin(y), (x, y, z) => Math.cos(x), (x, y, z) => z]); board.update();
